Savera Dhanraj, 17, a senior at Health Professions and Human Services High School in the East Village, was recognized for project analyzing heavy-metal concentrations on the beach in Howard Beach, Queens. (The beach tested negative.) Her mentor on the project was a Nazrul Khandaker, a geologist at York College.

At the international finals, Savera will be competing against about 1,300 other contestants for $4 million in prizes and awards; about a quarter of the contestants win something. City Room wishes Savera the best of luck.
